3 Claims.

invention relates to improvements in'soap ejecting spray heads. v

1` Heretofore, beauty parlor operators and barbers", whenshampooing apatrons hair, have been sil forced tofutilize soap from a separatebottle or cake; and it hasl been necessary to rst apply the soap, thento replace the bottle or cake of the latter, and` then to pick up thewater spray head; This inconvenient change must be made m several timesbefore the shampoo is completed.

Furthermore, with present day methods, the liquid soap is relativelycold while the water being used is warm.` Thus the patron is subjectedto to the discomfort of temperature changes Aeach T515' time the soap isapplied. It is one of the objects of the present invention to provide animproved spray head having means embodied therein for ejecting soap whendesired, thereby eliminating the usual inconveniences referred to above.

A further object of the invention is to provide a soap ejecting sprayhead wherein the soap chamber is so positioned relative to the waterinlet as to provide for warming'of the soap as the water passes thrusaid inlet.

A further object of the invention is to provide a device as abovedescribed which maintains the soap in a sanitary condition and which iseconomical in that it provides for discharge in controlled amounts asneeded.

A further object of the invention is to provide a soap ejecting sprayhead which is simple in construction, inexpensive to manufacture,durable, and well adapted for the purpose described. With the above and'other objects in View, the invention consists of the improved soapejecting spray head and all its parts and combinations as set forth inthe claims and all equivalents thereof.

In the accompanying drawing illustrating one complete embodiment of thepreferred form of the invention in which the same reference numeralsdesignate the same parts in all of the views:

Fig.' 1 is an elevational view of the improved v spray head, showing afragment of tubing conis preferably substantially bell-shaped; its lowerend being normally closed by a dished plate" 9 formed with aV pluralityof apertures IIIJ andi with a larger central aperture I-I". Theapertures IU are for the discharge of water inshower form, and theaperture II is a soap ejecting' outlet, as will be hereinafter explainedmore-inA detail. The peripheral edge of the plate Bf is flanged aroundthe flared lower'edge I2- ofl the housing as at i3, and the parts arethen pressed together to maintain the plate 9 rmlyin-y position.

At an intermediate point within the housirigfis a horizontal partitionI4 having a central apenture I5. A water inlet pipe IBhas its lower endlextending thru the partition I4 and held in place in any suitablemanner, such as by a nut I6. The upper end of the pipe I6 extends thruthe upper end of the bell-shaped housing 8 and is formed with a nippleI'I for the reception of one end of rubber tubing or the like I8.

The housing 8 is also formed near its upper end with an opening I9,there being a tubular boss 20 projecting from said opening. A cap 2| maybe hinged as at 22 and may be normally maintained by suitable yieldingmeans in closed position. By lifting up the cap, the chamber 23 abovethe partition I4 and surrounding the pipe I6 may be filled with suitableliquid soap.

A valve rod 24 within the chamber 23 is slidable thru an aperture 25 ina guiding lug 26 and has its upper end slidable thru an opening 21 inthe upper end of the housing 8, said end being formed with an exteriorlyaccessible knob or button 28. Above the bracket 26 is a coiled spring 29surrounding the valve stem 24, and a collar 30, fixed to the upperportion of the valve stem, is adapted to engage the upper end of thespring 29 when downward pressure is exerted on the button 28.

The lower end of the valve rod 24 extends thru an opening 3| in thepartition I4 and carries a valve member 32 below said partition. Saidvalve normally closes a plurality of apertures 33 to normally preventthe flow of soap from the chamber 23. When the valve stem is depressed,however, soap can flow by gravity thru the apertures 33 into a valvechamber 34 and from said chamber thru a conduit 35 leading to the soapdischarging aperture II of the plate 9.

In use, after the chamber 23 has been filled with liquid soap, thedevice is held over the patrons head in the usual manner. When the wateris turned on, it will ow thru the tube I8 into the pipe I 6 and 'betweenthe partition I4 and the plate 9. The water will then emerge in the formof a spray from the small apertures in the plate 9. After the patronshead has been suciently moistened, the water may be turned oi'l and theplunger 28 pressed downwardly to cause soap to ow from the dischargeopening Il, or the soap may be ejected while the water is flowing, ifmore convenient. Thus, soap in any quantity may be discharged merely bypressure on the knob 28, and the relationship between the soap and watermay be readily controlled thru the usual water control. Due to the factthat warm water is usually employed, this water iiowing thru the pipe I6will tend to keep the soap in the chamber 23` in a warm condition or atsubstantially the temperature of the water; so that the patron will notbe subjected to sudden temperature changes. This warming of the soap isalso Very important, as it makes it flow more freely by gravity andfacilitates lathering.

It may readily be seen that the device is simple toY operate, sanitary,and otherwise well adapted for the purposes described.

Altho only one form of the invention has been shown and described, it isobvious that various changes and modiiications may be made thereinwithout departing from the spirit of the invention; and it is to beunderstood that all of such changes are contemplated as may come withinVthe scope of the claims.

What I claim is:

1. A soap ejecting spray head comprising a casing having an aperturedlower end, a partition Within the casing spaced from said end andforming a chamber for liquid soap thereabove, means for admitting waterto the space between said partition and the. apertured end for dischargein the form of a spray, a conduit extending from the soap chamber to theapertu-red end of the casing and communicating with the exterior, andmeans independent of the iiow of water for controlling the fiow of soapthru said conduit.

2. A soap ejecting spray head comprising a casing having anaperturedlower end, a partition within the casing spaced from said endand forming a chamber for liquid soap thereabove, means for admittingwater to the space between said partition and the apertured end fordischarge in the form of a spray, a conduit extending from the soapchamber to a central portion of the apertured end of the casing andcommunicating with the exterior, and means independent of the flow ofwater for controlling the iiow of soap thru said conduit.

3. A soap ejecting spray head comprising a casing having an aperturedlower end, a partition within said casing spaced from' said end andforming a chamber for liquid soap there-
